My landlord increased my rent by $100, which in my opinion makes my apartment overpriced compared to similar apartments in the area.

At this point the value of the house is still increasing but not at the same rate as the previous years for a number of obvious reasons (high Interest rates,  age of house, etc.) and at this point I'm not sure what my next move should be since I don't like having all that equity tied up in the property and borrowing against it (HELOC) doesn't seem like a good idea since banks seem to be charging even higher than "normal" interest rates because the house is not my primary residenceIt's been almost 2 yrs since a I moved out of the house and I know my time is running out before we'll have to pay capital gains on the property if we chose to sell it [unless I do a 1031 exchange of course] but wondering what other options I might consider.

Conversely a restaurant could pay 200k in rent but do 5 million in sales for 4 percent rent to sales ratio.Typically lower rent and B to C sites only attract the smaller tenant off name franchisees.

Will keep them at gradual increases.

I would then keep the extra hours going towards increasing my pension, extra overtime hours that would have been spent on my rental, my year-end bonus would be bigger, and I can come it with a significantly higher cost basis lowering my tax liability.

The costs on your vacation rental could be quite high, pushing any increased return far into the future. 

Letting garbage pile up can also attract bugs and rodents.

Thus the reason why most people are much more successful on one platform versus another because as your booked rate increases so does your search ranking on that platform and then it continues to fuel itself. 

Talk to the tenants and ask if there have been any problems with the gas as the usage has increased compared to last year.Without separate meters, have each unit pay 50% of the bill assuming the units are similar size. 

I just heard back from the bank and her response to my inquiry I emailed and said"I'm not finding any information that the adverse market refinance fee is still active, I've only found information to the contrary.Linked article from The Federal Housing Finance Agency mentioning the fee has been done away with as of August 1, 2021"Her response"You are correct, no hit for Cash out on primary residence, that has gone away but we do have adjusters for Loan to value and cash out loan to value along with credit score and 2-4 unit"This is problematic to me on so many levels, why was she willing to increase my interest rate based on her ignorance, who is watching and making sure these lenders are doing the right thing?
